Dock Bug (Coreus marginatus) early stage nymph. Wherever there is dock (Rumex) you are bound to spot a few of these living on it, feeding on the fruits and seeds. They pass through five stages before becoming an adult as in the last image. Double-click to get closer still …

I have featured this extraordinary ‘bug’ before in a previous post, and you can learn more about it there if you wish to: Dock Leaf Bug. However, please note the two converging lobes on the nose in the second image down. This is diagnostic of this species.
When I came across several of them this morning on a local woodland margin, I also saw two instars which can be seen below. Note the differences between the adult on the left and the final instar on the right in the image directly underneath.
Below is a mid instar, and comparisons can be made between the two stages with the final instar above.
